NOTES:
1. Device is ratiometric within this specified excitation range.
2. Full Scale Span (VFSS) is defined as the algebraic difference between the output voltage at full rated pressure and the output voltage at the
minimum rated pressure.
3. Offset (Voff) is defined as the output voltage at the minimum rated pressure.
4. Accuracy (error budget) consists of the following:
Linearity:
Output deviation from a straight line relationship with pressure over the specified pressure range.
Temperature Hysteresis: Output deviation at any temperature within the operating temperature range, after the temperature is
cycled to and from the minimum or maximum operating temperature points, with zero differential pressure
applied.
Pressure Hysteresis:
Output deviation at any pressure within the specified range, when this pressure is cycled to and from the
minimum or maximum rated pressure, at 25
°
C.
Offset Stability:
Output deviation, after 1000 temperature cycles,
minimum rated pressure applied.
TcSpan:
Output deviation over the temperature range of 10 to 60
°
C, relative to 25
°
C.
TcOffset:
Output deviation with minimum rated pressure applied, over the temperature range of 10 to 60
°
C,
relative to 25
°
C.
Variation from Nominal:
The variation from nominal values, for Offset or Full Scale Span, as a percent of VFSS, at 25
°
C.
5. Auto Zero at Factory Installation: Due to the sensitivity of the MPXV4006G, external mechanical stresses and mounting position can affect
the zero pressure output reading. To obtain the 5% FSS accuracy, the device output must be “autozeroed’’ after installation. Autozeroing
is defined as storing the zero pressure output reading and subtracting this from the device’s output during normal operations.
